Severe bleeding after cystoscopy

Disease analysis: Hello, according to the information you provided, the purpose of the doctor's cystoscopy for your father is to understand the bladder condition, and at the same time, to do retrograde catheterization angiography to understand the cause of right urinary tract obstruction. Cystoscopy may damage the urethra and bladder, leading to bleeding. At the same time, your father has high blood pressure and prostatic hypertrophy, which will aggravate bleeding during cystoscopy. Suggestion: At present, your father's condition should be replaced with a larger urinary catheter and given continuous bladder irrigation. If he has convulsions and his mental state is not good, he should consider whether he has moderate or above anemia and need blood transfusion if necessary. For severe hydronephrosis in the right kidney, right kidney puncture and fistulation can be considered to reduce the pressure of hydronephrosis and avoid further damage to the kidney. If bladder bleeding persists, cystoscopy should be done again to determine whether it is caused by prostatic hyperplasia. If so, transurethral resection of prostate will be done.
